can operate up to 5Mbps. All of the differential
receivers can receive data up to 5Mbps.
Decoder
The SP503 has the ability to change the inter-
face mode of the drivers or receivers via an 8–bit
switch. The decoder for the drivers and receiv-
ers is not latched; it is merely a combinational
logic switch. The codes shown in Tables 1 and
2 are the only specified, valid modes for the
SP503. Undefined codes may represent other
interface modes not specified or random outputs
(consult the factory for more information). The
drivers are controlled with the data bits labeled
TDEC₃–TDEC₀. The drivers can be put into tri-
state mode by writing 0000 to the driver decode
switch. The receivers are controlled with data
bits RDEC₃–RDEC₀; the code 0000 written to
the receivers will place the outputs in an unde-
termined state. All receivers, with the exception
of SCT, do not have tri-state capability; the
outputs will either be HIGH or LOWdepending
upon the state of the receiver input.
